Amazon.com is working with the U.S. Postal Service to deliver packages on Sunday, starting in the Los Angeles and New York metropolitan areas. Amazon Prime members, who receive unlimited, free two-day shipping on millions of items, can now receive their packages on Sunday in these areas. Amazon and the U.S. Postal Service plan to roll out this service to a large portion of the U.S. population in 2014 including Dallas, Houston, New Orleans and Phoenix.

Amazon will also deliver SUnday packages in London later this month.
